2. The person identification device according to claim 1 , wherein the output unit performs processing to output, to a display device, display data to display an identification result obtained by the identification unit and the judgment result obtained by the group judgment unit.
3. The person identification device according to claim 1 , further comprising: a relevancy judgment unit which evaluates relevancies among a plurality of persons identified by the identification unit and which updates the attribute information of each person stored in the storage unit based on the evaluation of the relevancy between the persons.
4. The person identification device according to claim 1 , further comprising: wherein the output unit outputs information indicating each person identified by the identification unit, if the group judgment unit judges that the plurality of persons are present at the same time in the specified area.
5. The person identification, device according to claim 1 , wherein the output unit outputs a warning having a level set in association with the specified area to the external device, if the group judgment unit judges that the plurality of persons are present at the same time in the specified area.
6. The person identification device according to claim 1 , wherein the output unit outputs a warning having a level set in association with the specified area to the external device, if the group judgment unit judges that the plurality of persons are present at the same time in the specified area.
7. The person identification device according to claim 1 , wherein in a case where the plurality of persons belongs to the same group, and the biometric information of the plurality of persons is detected in the same period of time from image information successively input by a plurality of input units provided in respective areas to be determined as areas to be monitored, the group judgment unit judges that the plurality of persons are present in the same period of time.
8. The person identification device according to claim 1 , wherein in a case where the biometric information of the plurality of persons is detected from images picked up by a camera provided in the specified area, for a predetermined time period, the group judgment unit judges that the plurality of persons are present at the same time in the specified area.
9. The person identification device according to claim 1 , further comprising: a relevancy judgment unit which updates, if attribute information of the persons present at the same time in the specified area are different, the attribute information of the persons to cause the attribute information to be same as the attribute information of any one of the persons.
10. The person identification device according to claim 9 , wherein the relevancy judgment unit initializes the attribute information of the persons present at the same time in the specified area, if the attributes of the persons are different, and the attribute of any one of the persons is a predetermined attribute.
11. The person identification device according to claim 1 , wherein the larger the number of persons judged by the group judgment unit to be present at the same time in the specified area, the larger the number of external devices.
12. The person identification device according to claim 1 , wherein the larger the number of persons judged by the group judgment unit to be present at the same time in the specified area, the louder the output volume of the warning.
13. The person identification device according to claim 1 , wherein the larger the number of persons judged by the group judgment unit to be present at the same time in the specified area, warning information having a greater importance is output.
14. The person identification device according to claim 1 , wherein the larger the number of persons judged by the group judgment unit to be present at the same time in the specified area, the louder the output volume of the warning.
15. The person identification device according to claim 1 , wherein the larger the number of persons judged by the group judgment unit to be present at the same time in the specified area, warning information having a greater importance is output.
16. A person identification method of identifying a person, comprising: storing, in a storage device, at least one piece of biometric information of a registrant and attribute information indicating attributes of registrants that are associated with each other; obtaining information by monitoring at least one monitoring area via an image acquiring device; detecting the biometric information of at least one person from the information obtained by monitoring the at least one monitoring area; collating, via a processing device, the detected biometric information with the stored biometric information to identify the person associated with the detected biometric information; judging whether or not a plurality of persons having attributes set in advance are present at the same time in a specified area based on the obtained information of the at least one monitoring area and an identification result obtained from the detected biometric information; and outputting a warning having information and a level set in advance to an external device, if the judging determines that the plurality of persons are present at the same time in the specified area, wherein, when it is judged that the plurality of persons have the attribute of a single group, the warning information and level to be output are changed in accordance with the attribute of the group and the number of the persons.
17. The person identification method according to claim 16 , wherein the outputting performs processing to output, to a display device, display data to display an identification result and the grouping result.
18. The person identification method according to claim 16 , further comprising: evaluating relevancies among a plurality of identified persons, and updating the attribute information of each person stored in the storage unit based on the evaluation of the relevancy between the persons.
19. The person identification method according to claim 16 , further comprising: controlling information indicating each identified person for each group based on the grouping result, wherein the outputting outputs information indicating each identified person, the information being controlled for each group.
20. The person identification method according to claim 16 , wherein the outputting outputs the warning having a level set in association with the specified area to an external device, if it is judged that the plurality of persons are present at the same time in the specified area.
21. The person identification method according to claim 16 , wherein the outputting outputs the warning having a level set in association with the specified area, if it is judged that the plurality of persons are present at the same time in the specified area.
22. The person identification method according to claim 16 , wherein in a case where the plurality of persons belong to the same group and the biometric information of the plurality of persons is detected in the same period of time from the-image information successively input by a plurality of input units provided in respective areas to be determined as areas to be monitored, the judging determines that the plurality of persons are present in the same period of time.
23. The person identification method according to claim 16 , wherein in a case where the biometric information of the plurality of persons is detected from images picked up by a camera provided in the specified area for a predetermined time period, the judging determines that the plurality of persons are present at the same time in the specified area.
24. The person identification method according to claim 16 , further comprising: updating, if attribute information of the persons present at the same time in the specified area are different, the attribute information of the persons to cause the attribute information to be same as the attribute information of any one of the persons.
